MECHANICAL MOVEMENT FOR ORE CONCENTRATING AND SEPARATING APPARATUS.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed March 29, 1910. Serial No. 552,230.

To all whom it may concern:

Be it known that I, F RANQOIS DALLE- MAGNE, citizen of France, residingat Pasajes, in the Kingdom of Spain, have invented new and usefulImprovements in Mechanical Movement for Ore Concentrating and SeparatingApparatus, of which the following is a specification.

This invention consists in improvements in ore concentrating andseparating apparatus of the kind described in my Patent No. 953,900dated April 5, 1910.

The principal object of the invention is an improved form of the devicedescribed in the specification of the aforesaid patent for modifying theform of the circular movement given to the platform.

The improved device instead of being formed by a sector of which thepoint of connection with its operating lever can be varied is formed byan eccentric, the same variations of movement being obtained by varyingthe setting angle of the eccentric with regard to the operating lever.

The invention also comprises means for compensating inertia in the wholeof the machine.

In the annexed drawing: Figure 1 is an elevation of the oreconcentrating and separating machine with the device forming the objectof the invention mounted thereon. Fig. 2 is an elevation of the deviceon a larger scale. Fig. 3 is a horizontal section of Fig. 2 and Fig. 4an end view of the same.

On the cross shaft a mounted in suitable bearings an eccentric b iskeyed around which a bracket 0 which supports the table can turn freely.

The eccentric Z; is fixed to a sleeve (Z mounted on the shaft (4 andfixed to a recessed plate 6. In the recess of this plate a disk f ismounted fixed to a crank g and secured in place on said plate by meansof bolts h h. The plate 6 is provided with slots 1' concentric with theshaft a, which allows of turning it around the disk f to vary thesetting angle of the eccentric b. The eccentric b is oscillated by thecrank g, the oscillating movement being transmitted to the transverseshafts a (Fig. 1) parallel to the shaft a. For this purpose the shafts aalso carry eccentrics around which the brackets c supporting theplatform can turn freely. These eccentrics are provided with ank j jnnected. by a rod The crank j as well as the cranks j are formed onsleeves Z (Figs. 3 and 4) made integral with the eccentrics Z).

The crank g which actuates the eccentric b is given an oscillatingmovement by means of a slide block Z mounted on the fly wheel r of themotor shaft 8.

It can be understood from the foregoing description that by varying thesetting angle of the eccentric b the platform can be given movements ofvaried forms as with the apparatus forming the object of the principalpatent. The invention also provides means for facilitating the backstroke of the rod 70 so as to compensate the action of inertia, the saidmeans consisting in a spring m fixed at one end to the movable frame Pand at the other end to the frame 12.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In an ore concentrating and separating apparatus the combination of astationary frame a, a movable frame 1) arranged above said stationaryframe, cross shafts a a parallel one with each other and journaled inthe stationary frame, eccentrics fixed on the cross shafts, bracketsloosely mounted on said eccentrics and fixed to the movable frame,cranks j j made integral with the eccentrics, a rod 70 connecting saidcranks, operating means for imparting to the eccentric 6 fixed 011 thefirst cross shaft a an oscillating movement, and means adapted to varythe setting angle of said eccentric b with relation to its operatingmeans, substantially as described and for the purpose set forth.

2. In an ore concentrating and separating apparatus the combination of astationary frame a, a movable frame 79 arranged above said stationaryframe, cross shafts a a parallel one with each other and journaled inthe stationary frame, eccentrics fixed on the cross shafts, brackets c cloosely mounted on said eccentrics and fixed to the movable frame,cranks j 7" made integral with the eccentrics, a rod 10 connecting saidcranks, a recessed plate 6 ,made integral with the eccentric I? fixed onthe first cross shaft a, a disk f mounted in the recess of said plate 6,a crank g fixed to said disk f, means for securing the disk f in therecessed plate e and for varying the angular position of the latter withrela n t the former, and means for imparting to the crank 9 anoscillating movement, substantially as described and for the purpose setforth.

3. In an ore concentrating and separating apparatus the combination of astationary frame a, a movable frame 2) arranged above said stationaryframe, cross shafts a a parallel one with each other and journaled inthe stationary frame, eccentrics fixed on the cross shafts, brackets c cloosely mounted on said eccentrics and fixed to the movable frame,sleeves made integral with the eccentrics, cranks j formed on saidsleeves, a rod in connecting said cranks, a recessed plate 6 madeintegral with the eccentric Z) fixed on the first cross shaft a, a diskf mounted in the recess of said plate 6, a crank g fixed to said disk f,slots 2' formed in said plate concentric with the shaft a, bolts 7Ltraversing said slots and adapted to se cure the disk f in the recessedplate after it has been set in its desired angular position withrelation to the disk, and a slide block Z engaging the crank g andmounted on the fly wheel of the motor shaft so as to impart anoscillating movement to said crank g, substantially as described and forthe purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
